【摘要】 陕西西咸新区是国家第一批海绵城市建设试点城市之一,对西咸新区沣西新城试点区域内市政道路采用了生态滤沟、植草沟+雨水花园、透水路面、路基防护等设计。该工程建成后,经历了一次强暴雨,结果表明,排涝效果显著,平均雨水径流削减率达70.5%,对类似区域海绵城市道路设计及建设具有一定参考价值。更多还原

【Abstract】 Xixian New Area of Shaanxi Province is one of the first pilot cities for sponge city construction in China. This paper gives detailed introduction to the designing of typical roads in pilot area,such as ecological filter ditch,grassed swale + rainwater garden,permeable pavement,roadbed protection etc. The road experienced one strong storm after construction. The results showed that the effect of drainage was great,and the average reduction rate of rainfall runoff was 70. 5%. So the construction process of the road provides certain reference value for designing and construction of sponge city roads in similar areas.更多还原
